Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to a receptacle connector that can absorb heat generated by a terminal in a high current operating environment to ensure proper operation.

A conventional socket connector includes an insulative housing having a tongue and a plurality of terminals retained on the insulative body tongue. When such connectors are used in high current operating environments, or when subjected to high current simulation tests prior to use, the heat generated by the high currents causes the terminal temperature to continue to rise for up to half an hour. A temperature difference of more than 30 degrees Celsius before and after the terminal test will cause the socket connector to malfunction.

In view of this, it is indeed necessary to provide a socket connector that absorbs heat generated by a high current to ensure proper operation to overcome the drawbacks of the prior art.

As a further improvement of the present invention, the insulating body is made of a heat conductive material and is integrally formed with the heat absorbing member for absorbing heat on the terminal.

As a further improvement of the present invention, the insulative housing is provided with a receiving slot, and the heat absorbing member is received in the receiving slot.

As a further improvement of the present invention, the heat absorbing member is injection molded on the insulating body or assembled into the receiving groove.

As a further improvement of the present invention, the terminal is provided with a welded portion welded to the circuit board and a main body portion connected between the welded portion and the contact portion, and the holding portion is provided at the main body portion.

As a further improvement of the present invention, the insulative housing is provided with a receiving space and a base connected to the tongue plate, and the insulative housing further includes a top wall, a bottom wall and a pair of side walls surrounding the receiving space. The contact portion of the terminal faces the bottom wall, and the receiving groove is disposed on the base portion and the bottom wall. The base portion is provided with a holding table corresponding to the receiving groove, and the terminal welding portion is held in a row on the holding table.

As a further improvement of the present invention, the holding portion of the terminal is attached to the surface of the heat absorbing member.

According to a further improvement of the present invention, the heat absorbing member is provided with a plurality of clamping portions and a plurality of clamping grooves formed between the plurality of clamping portions, and the holding portion of the terminal is at least partially received in the clamping groove The inside is clamped by the clamping portion.

As a further improvement of the present invention, the heat absorbing member is made of a heat dissipating adhesive, or silicone rubber, or blush.

Compared with the prior art, the electrical connector of the present invention is used in a high current working environment. Or when performing high current simulation tests before use, the heat generated by the high current causes the terminal temperature to rise. At this time, the heat of the terminal is greatly absorbed by the heat absorbing member. The terminal temperature does not rise by 30 degrees Celsius, so that the electrical connector remains functional.

Referring to the first to sixth figures, the electrical connector 100 of the present invention includes an insulative housing 1 provided with a receiving space 10, a plurality of terminals 2 held on the insulative housing 1, a metal reinforcing member 3, a holding piece 4, and mounting. Part 5 and heat absorbing member 6.

The insulative housing 1 is provided with a base portion 11 and a tongue plate 12 extending forward from the base portion 11. The insulative housing 1 further includes a top wall 13 , a bottom wall 14 , and a pair of side walls 15 surrounding the receiving space 10 . The insulative housing 1 is provided with a receiving groove 16 extending to the base 11 and the bottom wall 14. A holding table 17 is provided at the receiving groove 16 of the base portion 11. In the present embodiment, the top wall 13, the bottom wall 14, and the pair of side walls 15 are integrally formed with the base portion 11. In other embodiments, the top wall 13, the bottom wall 14, and the pair of side walls 15 are separately formed from the base portion 11 and then assembled with the base portion 11.

The terminal 2 is provided with a contact portion 21 for exposing the tongue 12 for contact with the mating connector, The welded portion 23 welded to the circuit board and the main body portion 22 provided between the contact portion 21 and the welded portion 23. The terminal 2 further includes a holding portion 221 . The holding portion 221 is a part or all of the main body portion 22 .

The upper surface of the heat absorbing member 6 is provided with a plurality of holding portions 61 and a plurality of holding grooves 62 formed between the plurality of holding portions 61. The rear end of the heat absorbing member 6 forms a step portion 63. The heat absorbing member 6 is made of a heat dissipating adhesive, or silicone, or blush, or other heat conductive material.
